PerfCountInfo Element Documentation

NAME

PerfCountInfo -- Click element; turn on Pentium Pro performance metrics

SYNOPSIS

PerfCountInfo([METRIC0, METRIC1])

Drivers: linuxmodule
Package: linuxmodule (core)

DESCRIPTION

The Pentium Pro CPU can maintain up to two performance counters. PerfCountInfo turns on those counters. METRIC0 is the type of performance counter 0, METRIC1 is the type of performance counter 1. Either type may be empty, in which case that counter will not be used. The SetPerfCount and PerfCountAccum elements automatically turn on the relevant counters, so PerfCountInfo is not normally needed. It is useful if you are instrumenting individual elements.

NOTES

Valid performance metric names are BUS_TRAN_INVAL, BUS_TRAN_MEM, DCU_MISS_OUTSTANDING, IFU_FETCH, IFU_FETCH_MISS, IFU_MEM_STALL, INST_RETIRED, L2_IFETCH, L2_LD, L2_LINES_IN, L2_LINES_OUT, L2_LINES_OUTM, and L2_RQSTS.

SEE ALSO

SetPerfCount, PerfCountAccum, SetCycleCount, CycleCountAccum
